Add `server-jre` software definition

This variant of the JRE will is better suited for server environments. 
The Server JRE includes tools for JVM monitoring and tools commonly

add `whitelist_files` data to JRE software definitions

This change requires Omnibus 1.2.0+. This was the first version of

Previously this data was hard-coded in the core Omnibus framework!
